nylamino) -phenyl beta-naphthylamine, p-acetamino diphenylamine, p (p toluene sulfonylamino) diphenylamine, p-(p-toluene-sulfonylamino) -phenyl p-tolylamine.

Particularly efiective are para-(para-toluene sulfonylamino) diphenylamine (CHPQWGNHQ) and its homologs such as para-(para-toluene sulfonylamino) -phenyl para-tolylamine The following tests made on pieces of cotton duck, exposed to the action of sunlight and the mercury vapor sunlamp, when treated with the present chemicals are shown below. The tensile strength and bursting strength are in pounds per square inch.

Filling tensile strength Bursting strength Cotton duck unexposed Cotton duck exposed 2 months on me g Cotton duck treated with 5% solution of para (toluene sulfonylamino) phenyl-para-tolylamine exposed 2 months on roof Cotton duck treated with 2% sol. of para (toluene sulionylamino) phenyl para-tolylamine exposed 2 months on roof Cotton duck treated with 1% sol. of para (toluene sulionylemino) phenyl para-tolylamine exposed 2 months on roof Cotton duck treated with 5% sol. of para (toluene sulionylannno) diphenylamine, exposed 2 months on roof Cotton duck exposed 3 months on me Cotton duck treated with 5% sol. of para (toluene sulionylamino) phenyl para-tolylamine; then exposed 3 months on roof Cotton duck exposed under mercury vapor sunlamp during 144 hours Cotton duck treated with 5% sol. of para (toluene sulionylamine) diphenylamine, exposed under mercury vapor lamp 144 hours Examples of aminodiarylamines the acidyl derivatives of which are included within the scope of the invention are p-amino-diphenylamine; p-amino-phenyl tolylamines, for example, p-amino-phenyl o-tolylamine and paminophenyl p-tolylamine; mono-beta-naphthyl-p-phenylene diamine, mono-alpha-naphthyl-p-phenylene diamine, mono-beta-naphthylm-phenylene diamine, and mono-alpha-naphthyl-m-phenylene diamine; and examples of acidyl groupings are those from formic acid, acetic acid, butyric acid, stearic acid, benzoic acid, furoic acid, carbonic acid, phthalic acid, succinic acid, maleic acid, malonic acid, benzene sulfonic acid, toluene sulfonic acid, and oxalic acid. Carbonic, phthalic, succinic, maleic, malonic, and oxalic acids are examples wherein the acidyl group is di-valent and is to be combined with two moles of the chosen amino-diarylamine.

The chemicals may be applied in the form of solutions or emulsions, but preferably in solution in some suitable solvent, to all manners of textile goods that usually deteriorate when exposed to sunlight such as sails, tents, awnings, clothing, sports shoe fabric, netting used in agriculture to protect plants, rope, etc.

Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. A process of stabilizing cellulosic fibrous textile materials against deterioration which comprises treating the same with an acidyl-amino diarylamine.

2. A process of stabilizing cellulosic fibrous textile materials against deterioration which comprises treating the same with para-(para-tolue'ne sulfonylamino) diphenylamine.

6. Cellulosic fibrous material containing in combination with the fibres thereof an acidylamino diarylamine, whereby to stabilize the fibres against deterioration.

7. Cellulosic fibrous material containing in combination with the fibres thereof an aryl sulfonylamino diarylamine, whereby to stabilize the fibres against deterioration.

8. Cellulosic fibrous material containing in combination with the fibres thereof a toruenesulfonylamino diarylamine, whereby to stabilize 10.
